### Real Numbers - Activity 3 - Let's examine the Patterns! ADDITION of Negative Numbers

Enter formula to find the value of "a + b".
From the numbers generated, write down the 2 rules of Addition of Integers.

Vocabulary List
• Numerical Part
• Sign
• Positive
• Negative
• Difference
• Sum
• Same
• Different

1. I'm not sure if this counts:

1. If you add 2 even numbers or 2 odd numbers, the sum would be even

2. If you add 1 odd number and 1 even number, the sum would be odd

2. 1. If a negative number is added to the same number in positive, the answer will be 0.
(-n)+n=0
2. If 0 is added to a negative number, the answer is the negative number.
0+(-n)=(-n)

3. 1. If a positive number is added to a negative number, the number will only be 0 if the two numbers have the same digits.An example is:
positive 1+(-1)=0

2. The sum of two negative integers is a negative integer.An example is:
(-3)+(-5)=(-8)
Rather than the number reduce to be a smaller value, the number increases to a bigger value in the terms of negative.

4. 1. The sum of the same numerical part of a negative number and a positive number will be 0. Eg.(-y)+y=0 OR (-3)+3

2. The sum of two different negative numbers always results in a negative number. Eg, (-y)+(-x)=(-y)+(-x) OR (-4)+(-5)=(-9)

5. *numerical part meant to be numerical value

6. (-n)+(-y)=(-n)-y
n+y=n+y
n-(-y)=n+y
